I think this is correct, to an extent. But consider handling an egg while your arm is numb. It would be difficult. But perhaps a great benefit of tactile input is its simplicity. Instead of processing thousands of pixels, which are passive to interference from changing light conditions, one only has to process perhaps a few dozen tactile inputs.
